Possible Causes
Blocked ventilation under cooktop, Overheated induction module, Failed NTC temperature sensor on module, Continuous high‑power operation without cooling
How to Fix / Troubleshooting
Safety first: Turn off the cooktop and allow it to cool completely. Disconnect power at the breaker before removing any panels.
- Allow cooling: Leave the cooktop off for at least 30 minutes to allow internal components to cool. Restart and test.
- Check ventilation: Ensure cabinetry below the cooktop meets La Cornue clearance requirements and that vents are not blocked by drawers or stored items.
- Clean intake/exhaust: If accessible, vacuum dust from ventilation grilles and around the cooling fan.
- Inspect fan operation: With power restored and a zone on medium power, listen for the cooling fan. If it does not run, the fan or its supply may be faulty and should be replaced.
- Module replacement: Persistent E1 with proper ventilation suggests a failed temperature sensor or module; replacement of the induction power module is typically required.
